me-amazon@example.com
me-ebay@example.com
...
me-ANYTHING@example.com
or the other way around, if you preferred:
ebay-me@example.com
amazon-me@example.com
...
ANYTHING-me@example.com
You also want this to be flexible and work as a 'catch-all' for any addresses you have as your suffix or prefix - you don't want to have to log in to the control page each time you want to create a new prefix/suffix.
(you can also use a '''+''' instead of a '''-''' if you wanted to - just alter the settings appropriately below)
This is all possible with two things:
#(optionally) A sieve filter - to magically sort these messages in to their own IMAP folder
==Alias==
==Sieve filter==
Optionally, you can magically move these messages in folders...
Once messages are being sent to your Inbox, we create a sieve filter to automatically move messages to their folder, if it has been made. If the folder hasn't been made, then they will be put in to your Inbox as normal.▼
▲Once messages are being sent to your Inbox with the alias above,
<syntaxhighlight>▼
<syntaxhighlight lang="sieve">
require ["fileinto","imap4flags","variables","regex","mailbox"];
## Move messages sent to an address with a suffix eg, me-amazon@example.com in to a folder called Filtered/amazon, if it exists.
if exists "X-Delivered-To" {
if header :regex "X-Delivered-To" "-([A-z0-9]+)@" {
set "suffix" "${1}";
fileinto "INBOX.Filtered.${suffix}";
}
}
▲ stop;}
</syntaxhighlight>
*This filter uses the 'X-Delivered-To' header which is added by the A&A mail servers - even if you are BCC'd then the filtering will work. The X-Delivered-To is the 'envelope-to' header, which is the address the email was actually sent to by the sender (in lowercase).
*You'll need to add this sieve filter - eg by using the (latest) Thunderbird Sieve extension, see [https://support.aa.net.uk/Sieve_Filtering#Sieve_Server_Settings Sieve_Server_Settings] for info in the 'Creating Sieve Filters' section
*
==
You can create the folders automatically if you wanted add :create, - but some mail clients won't refresh their folder list until they are restarted, or the folder list collapsed and reopened. We also title case the new folder name - eg it will be called Amazon (capital A).
<syntaxhighlight lang="sieve">
set :upperfirst "suffix" "${1}";
fileinto :create "INBOX.Filtered.${suffix}";
▲</syntaxhighlight>
If you're using a + rather than a - to separate the suffix, then adjust the regex in the sieve filter above to be like:
<syntaxhighlight lang="sieve">
if header :regex "X-Delivered-To" "\\+([A-z0-9]+)@" {
</syntaxhighlight>
== Create the folders ==
The sieve filter puts email in to a folder called Filtered/XXX, and as long as XXX matches the suffix in the email address, the messages will get moved to there.
So in your email program:
